Background technology
A problem that runs into through regular meeting in old building modernization restructuring engineering is that legislative control on safety is through changing for many years but existing lift well bottom can not provide enough survival spaces to satisfy the requirement of current legislative control on safety.As a rule, not that too costliness is exactly technical can not the realization by transforming in vertical shaft bottom formation more space.For these reasons, adopt the safety approach that needs as far as possible little space usually.
In existing technology, if possible, lift well bottom survival space is to have the survival space of enough degree of depth to realize by making the hole form one, makes " the safe square " of the desired 500*600*800 at least of elevator regulations mm size can be at least hold wherein under the situation that minor face makes progress.The shortcoming of this solution has been to increase the degree of depth in hole, and particularly in modernization restructuring, has increased the difficulty and the construction cost that form the hole.
In existing technology, if can not increase the degree of depth in hole, adopted method is that various safety buffers and upholder are installed on the hoistway wall of the bottom in hole or next-door neighbour bottom, and these devices can be raised or be changed into stand up position, to allow to carry out upkeep operation.Another kind method is that elements such as the pin that will be for example be shaped or analogue are secured to the motion that guide rail is used for stopping elevator cage.
International patent application no WO 99/47447 (FI 980594) has disclosed a kind of safety device that can realize above-mentioned purpose in the elevator maintenance operation process, guarantee survival space in the lift well.In this solution, lift well is provided with the safety buffer that is lying status under normal operation in silo bottom, when the elevator maintenance personnel enter work of lift well carrying out maintenance or similar work from the bottom safety buffer is raised to stand up position.The length of safety buffer so design makes that under failure condition, elevator cage or counterweight can not descend to such an extent that too much the personnel that are in silo bottom are damaged.The shortcoming that this method exists is, even safety buffer and their pivot structure also can occupy the certain space of silo bottom under the elevator normal operating state, so this method is under the narrow situation in silo bottom space and should not adopt.
International patent application no WO 97/23399 has disclosed another kind of existing solution.In this solution, a safety system that is arranged between elevator cage and the hoistway wall can stop at elevator apart from silo bottom certain altitude place in needs.This safety system comprises the stop element that is fixed on elevator cage outer wall or the cab framework and is installed in the support beam with certain-length of silo bottom.For normal elevator operation, the support beam below stop element can be diverted on one side.Safeguard, before inspection or the similar operations, support beam is changed into stand up position, thereby prevents that elevator cage from descending too much in vertical shaft.Because this solution needs several stop elements, switch and other parts to realize, so its shortcoming is complex structure and cost height.
Generally speaking, special energy disperser layout has the expensive and complicated shortcoming of structure.The total further deficiency of special energy disperser and other support scheme is that they can limit the stroke of elevator when safeguarding, make the stroke of elevator shorter than the stroke distances from top layer to bottom.Therefore, during the examination and maintenance process, elevator can only be driven through than whole normal travel apart from short distance.
Summary of the invention
The objective of the invention is to eliminate above-mentioned shortcoming and realized a kind of economy, the reliable and wieldy method and apparatus that can form survival space in the lift well bottom.The inventive method is a feature with the content that is expressed in claim 1 characteristic, and apparatus of the present invention are feature with the content that is expressed in claim 5 characteristic.Other embodiments of the invention are feature with the content in the claim that is expressed in other.
The advantage of method therefor of the present invention is, even utilize simple structure just can provide the survival space that meets standard in the bottom of the lift well of low-rise building.The modernization restructuring that is applicable to elevator that the solution of this invention is fabulous, particularly so-called Backpack type elevator, wherein energy disperser and car hanging point all are positioned at the rear portion of cab, and following space, cab bottom is that continuous space does not have cab framework center support frame and do not have energy disperser in the centre in hole.Further advantages are not need extra structure in the bottom in hole, and the degree of depth in required hole is very little, thereby allow lift car to descend when normal running as far as possible far.The hole also needn't have greater than the ordinary buffer device and the required degree of depth of path.Another advantage of this invention is, safeguard with checked operation during identical in the distance moved and the normal running, thereby reliability improves.
Description of drawings
By example the present invention is made detailed decipher below with reference to accompanying drawings, wherein
Fig. 1 simplifies the elevator cage that view shows need have solution now with the section side-looking,
Fig. 2 simplifies view shows according to security solution of the present invention with the section side-looking.
The specific embodiment
In the scheme that Fig. 1 showed, the elevator cage of being seen 2 is in the position near bottom 4 in lift well 1.Although have only term " elevator cage " to be used in the following description, but it is meant all types of cab solutions, for example the sort of elevator cage that framework is arranged.For " safe square " 9 needed spaces that meet elevator standard are provided, just need elevator cage 2 to stop fully in " safe square " top.In the method for Fig. 1, need the special safety buffer or the support beam that use in the prior art, or cheat 5 and must do deeplyer on demand.
Fig. 2 showed based on solution of the present invention, and wherein the weight tray 3 of elevator cage 2 or its part are arranged to and can be turned to stand up position or near stand up position around articulated joint 8.Articulated joint 8 as hinge is positioned at the elevator cage forward edge, makes that when base plate 3 rose to stand up position, it prevented to enter simultaneously elevator cage during attended operation.
Elevator cage provides a limit switch 7, and it is arranged to, and base plate 3 can starting limig switch 7 when base plate 3 is positioned at the raised position of expection.This solution makes attended operation just can carry out after limit switch 7 is activated.This can guarantee that base plate can not rest on the normal operating position and the inlet that enters elevator cage can be prevented from when attended operation.
As extra preventive, elevator cage is provided with a horizontal safety pressing plate (safety batten) 6, and this safe pressing plate is arranged near the joint between rear wall and the base plate and installation in position always when base plate is in the normal position.Safe pressing plate 6 is so installed and is made it to be discharged by a certain size the power that makes progress that puts on base plate.Therefore, when being in the staff of silo bottom, the power that is applied on the base plate from below can discharge safe pressing plate at elevator cage just in case to the whereabouts, and base plate can upwards rotate around its articulated joint 8.
Utilize the method for this invention, lift well bottom survival space be by drive elevator cage 2 to the vertical shaft the appropriate location and promote cab base plate 3 to realizing that in the elevator cage its lowermost position required survival space height forms.The lifting of base plate preferably by with its rear rim around the hinge 8 that is in cab forward edge place upwards rotary bottom plate realize.When base plate was in the position of expectation, elevator device was apprised of base plate 3 by limit switch 7 and has been in and is used to safeguard or the position of similar operations.Base plate can be by hand hoisting.For this reason, safe pressing plate 6 at first is released, and after this, base plate is turned to its raised position, and base plate can be locked in this position.
